Lie it known that I EDWARD E. citizen of the United 5% the borough -"-'imiliefia: State of New ikii'k, new and useful lni Heating Systemsfnf a speeifieznjioni My invention relates to steam heating systems of H kl. l 0 casionally referred to indireel stems; and is pariiew Genn 95, residing in city, calmly, and have invented certain which he fellowing is can" e larly applienhle in heating SYS'i'GHlS for use in heating the ears of railway trains.

The invention heen particularly (le signed with reference to the heating OI" sieel railway cars, and is shown in the accompanying drawings invconnection with a car of such eonsu'ueiieii.

An important object of reduce The weight of he the invention is to heating system inhenting ystem 15 stalled in the can enghout the entire maintained in the can u year, and during a @0115" year it is not required for heatingthe 111'. Bnt during all 9 this H1116 it must he ti-inspoi'ted with the can as dead weight. The weight of such an, fem whether in use 01' not furnishes a large zii'ldil'iun to l'he weight of the 1321, and its ii'nnspnriniiun 2i sllhjeel' of consideable expense in the railway m2npanies.

in 'i'ih 1241!: uniformly heated. laflgiiiulinul lzlLllziIlD" i ii i view of a steam heating system according to and its connections partly in plan and partly y 2 heating system below the car floor taken on g5, 8 is a vertical longitudinal section through my parts; Figs. 11 and 11 are detail views and are there connected to a valve Ki The said valve is illustrated in Figs. 3, 4 and 5.

It is provided' with passages 70 (Fig. 4) which extend from the said return pipes J J to a screened pipe Z leading to traps L. 70 The said traps L are ordinary thermostatically controlled T-traps for disposing of the condensation water, and their construction forms no part of the present invention. Gravity traps M may-well be situated in communication with each of the said passages k 70 The valve K is provided with a central bore in which slides. the valve proper k controlled by a handle is or by its usual extension handle k Ports k 70 connect the passages 70 is with said central bore when the valve 70 is raised. 1'

It will. be seen from the foregoing that when the steam escapes through the passages k k of the valve K and through the T-traps L, that the return pipes are entirely disconnected from each other and are independent in their operation. The T-trap contains a thermostatic vessel Z which is partly filled with a volatile fluid and is adapted to .eXpand when steam passes through the return pipe, and seat itself against the seat Z closing the pipe Z. When the condensed water collects and cools the 5 thermostat it will contract and withdraw from seat Z under influence of spring Z and the pipe Z will'then be'open and permit the escape of the condensed water. The systems will then operate pressure systems. 1 0

'The following means enable the system to be operated as a vapo1"system:-The-valve K is provided with an outlet 70 which when the system is operating as a pressure system, is closed by the valve 70 This outlet com- 1 5 municates with a drip pipe or horn N, Fig.

I have illustrated my invention as applied to a steam heating system wherein steam is supplied to the radiating systems located within various cars from the train-pipe thermostat O. This as illustrated iscom- 45 A wh. .ds the length of the train, posed of'a coil 0 wound -about the horn and and is s with steam from the locomofilled with a liquid which boils at a low temtive be r anches A are connected to perature. A screen 0 surrounds the said 1 thermostat O to admit atmospheric air and render the same quickly responsive to changes in temperature. The dri pipe N has openings n rendering the tiermostat responsive to the temperature within the drip. The upper end of this coil 0 is connected by tube 0 to a thermostatic chamber 0 having the usual diaphragm 0 which bears upon the head of valve stem 0*, and closes the valve P in the steam supply pipe A A spring-p maintains this valve normally open, and the thermostat O operates to close the valve against the pressure of this spring.

55 1, each car contains four of such steam heating systems, each of which may be operated independently of the others, and they are illustrated as being divided, so that two of such radiating systems are located upon 60 each side of the car. Each of such radiating systems is illustrated as double branched, "having branches 0 0 each of-which has a lower return. pipe a c.
